A new nutritional assessment in patients with oral and maxillofacial malignancies

Combined subjective and objective nutritional assessment was performed on admission in 127 patients with oral and maxillofacial malignancies. On the basis of the nutritional assessment result, three typical nutritional parameters-body weight (BW) (X1), mid-upper-arm circumference (MAC) (X2), and hand grip strength (HGS) (X3) were used to establish a new nutritiona1 assessment method that was developed by a computer-based disricminant analysis. The established model was as follows: Y1=−126+1.09X1+1.34X2+0.23X3; Y2=−95.63+0.96X1+1.17X2+0.19X3. In the model Y1 was regarded as good nutrition and Y2 as malnutrition. The larger value of Y stood for the patientʹs nutritional status (i.e. Y1>Y2, well nourished; Y1
